provided with spacer portions 27--28, and 31-32, The scoring operation may be performed sias indicated. The liners for the top and botmultaneously with, or after the cutting operatom are also similar and are also in the nature tion. In the event it is performed after the F of flaps 34 and 40 formed as upper and lower cutting operation, the upper edges of naps 18 and 10' 22, and the lower edges of flaps 26 and 30, being aligned as indicated, form guides for the cut blank as it is fed or placed in the scoring device. Further describing the cut and scored blank, it will be seen that two of the liners, namely, liners 26 and 30, formed as lower extensions of their respective walls, are as wide as the inside of the container, that is to say they are substantially of the same width as the walls from which they extend. The other two wall liners, namely, liners 18 and 22, and the top and bottom lines 34 and 40, are narrower than the walls from which they extend. This dimensioning assures proper cooperation of the parts, as will presently appear. Further, it will be observed that the scrap stock is only a small percentage of the `entire blank, which is of course, a desirable feature.

After the blank is completely cut and scored, as above described, it is preferably provided on a. portion of edge 1 4 with a. strip of sealing tape or the like, referenced 50. The tape is secured to the invisible surface of the blank on the left hand portion of the side wall 11 and has an extending portion whose visible surface is coated with adhesive, substantially as shown. The blank ink this form, with sealing tape 5,0 attached thereto, may then be folded on the fold lines between walls 11-10, and 12-14, so that wall 14 will overlie wall l2 and wall 11 will overlie wall 10. This brings edges 1--4 and 2-3 into juxtaposition, and the extending portion of the sealing tape is then allowed to overlie the adjacent portion of wall 14 and be adhered thereto, to form a completely fabricated container, ready to .be assembled.

It is contemplated, at present, to ship containers from the container factory to the container using establishment, namely, the packer, with the containers in the-blank form of Figure 1, leaving the last mentioned operation to beA "a partially folded condition, with sealing tape 50 adjoining walls ll and 14.

In order to set up a container fromthe folded condition, wherein walls l1 and 14 are joined, it is rst necessary to fold` the side wall liner flaps 26 and 30 into the container, and upwardly,

through arcs of about 180., from the position they occupy in Figure 2, the liners then being.`

positioned to occupy the positions of Figure 4. Portions 2'7 and 28 of liner 26 will space the latter from wall 1l to form an air space therebetween, and portions 3l and 32 of liner 30 will similarly space the latter from wall 12. Then the bottom wall liner 40 is turned upwardly through an arc of about 90 from the position of Figure 2, to the position of Figure 5, with its portions 41, 42, and 43 serving to locate and seat liner 40 properly. The bottom is then completed by turning bottom wall 16 upwardly from the position of Figure 2, through an arc of about 90, to the position of Figure 5.

After the lower flaps are turned upwardly, as just described, the front and back wall liners 18y and 22 are folded downwardly and inwardly into the container, from the positions of Figure 2, through arcs of about 180, to the positions of Figure 5. Their portions 19 and 23, 20 and 24 will locate the liners and space them from walls 10 and 14 to form air spaces adjacent these walls, and their portions 20 andV 24 will seat Athe corner construction.

themselves between the edges of liner 40 and the walls 10 and 14, for similar purposes.

When the four lower flaps are turned upwardly and inwardly, and the two upper flapside wall liners are turned downwardly and inwardly, there is formed a complete container having an open top through which the container may be loaded, the contents then resting upon the bottom 40, in turn supported by its portions 42 and 43. After the container has been loaded, it may be closed by turning the top liner 34 and the top 15 inwardly to the positions of Figure 4, substantially as indicated. The container may then be sealed in any suitable fashion, not here described specifically.

A novel feature, best disclosed in Figure 7, is As indicated in this figure, the portion 28 of liner 26 is cut off square, and projects to and engages the inside surface of walll 14. The portion 23 of liner 22, however, is miter cut on line 5l, and portion 23, extending from wall 14, overlies a corner of portion 28, the net effect being to produce a lap joint at this point which gives the appearance of a miter joint. A similar joint is formed at the upper corner of walls ll and 10. True miter joints are formed at all other corners and these are not specifically described, other than to mention that they are formed by the indicated notch cutting of liners 26 and 30, these cuttings coif operating with miter cuttings on other liners.

While throughout the foregoing, the container has been described as formed from a single blank, it is apparent that the top and bottom liners may be formed of separate pieces, prop- 7,

erly shaped to cooperate with the remaining parts and to form a container similar to the one formed by the blank of Figure 1. In this Varia* tion, whereas four of liners will be integral with the walls, two of the liners, namely, the top and l bottom liners, will be separate. Further, if desired, the container need not be provided with top and'bottom liners at all or may be provided with but one of them, depending upon the desires of the user.

Stillafurther, if desired, the air spaces between the walls and their liners may be provided with an insulating packing, such as for example, cellulose, excelsior pack, etc. These may be placed in the air spaces separately or they might 7 be arranged in one integral and continuous strip long enoughto extend along the blank from edge l-4 to edge 2 3, and as wide as the height of the walls, this form of strip being placed on and glued to the blank of Figure l so.

as to cover walls l0, 11, 12, and 14. Then when the container is set up, the strip of packing is folded along with the walls, and disposes itself in a continuous band of insulation around the n inside of the walls of the container.

It will be observed at this time that when a strip of packing is laid along the portions 11-10-12-14 of the blank, and adhesively secured thereto, as is at present contemplated, portions of the strip, adjacent the container corners, will be crushed when the blank is folded. For this reason, it would be well to cut away the right hand edge of liner 26 and the left hand edge of liner 30, to narrow these liners and permit clear spaces to be formed near the container corners, these spaces then permitting the strip of packing to curve itself around the inside of the container,A near the corners, without its being crushed.

rIlhe container disclosed facilitates the adoption of a new process of refrigeration, now to be described. A manufacturer of solidified CO2 may ship a sealed unit, consisting of the container and a block of CO2, to a consumer, whothen places the unit, container and all, in a refrigerator. The container might well be provided with a number of partially scored but normally sealed openings, any desired number of which may be opened to permit escape of CO2 gas, the number depending upon the desired rate of refrigeration. The container permits the solidified CO2 to be shipped, without appreciable deterioration or diminution, and also permits the block of CO2 to be placed in the refrigerator, without there being a possibility that the consumer can be injured by manual or bodily contact with the naked block of CO2. The container cutouts or openings permit of a variation of the refrigeration rate. This process is believed to be novel and is facilitated by the efficient and practical container disclosed and herein claimed.

Further if desired, the bottom and/or the top liner may have holes punched therein to form seats for contained products, such as bottles or the like. These holes may be formed when the blank is cut and their provision entails no considerable expense. Further, if desired, especially where the container is used to ship a commodity such as solid carbon dioxide, or where it is used to ship refrigerated products, holes may be provided in certain of the liners to assist in the circulation of air, wherever circulation is desired. In that event, the gas given off by the carbon dioxide will pass through the holes and into the spaces between the liners and the walls, to fill these walls with the gas and thus to form gas filled insulating chambers.

Further if desired, the top and bottom liners may be provided with portions extending from portions 37 and 43 to engage portions 28 and 24 there adjacent, and thus to limit the inward movement of the top and bottom liners.

Further, if desired, the container may be used as a multi-cell container wherein one cell contains a refrigerant and the other contains contents to be refrigerated. For example, the container may be used to ship ice cream, in which case, small blocks or the like of solid carbon dioxide, might be placed in the bottom space, between liner 40 and the bottom 16, the ice cream being` placed in the interior of the container, on top of liner 40. The refrigerant may be placed in its compartment, which may then be sealed, and then ice cream may be placed in the interior of the box and the top sealed. In order to get at the ice cream, then, the user would not have to come in contact with the refrigerant, but may get at the ice cream merely by opening the container top.

The container might also be used for shipping fruits, or the like. The liners would thus prevent outside shocks from reaching the contained products, and the air spaces adjacent the liners would serve to insulate the contained products from outside weather conditions.

The container might also be used to ship delicate articles, such as radio sets, lamps, etc., the liners serving to insulate the contents from shocks against the walls of the containers.

From the foregoing, it will be observed that there has been provided a novel shipping container, characterized, by its having air-space forming liners for four or more walls, the liners and the Walls being integrally formed from a single blank, without complications or dimculties of manufacture.
